T WALTER B. TEMPLETON, OF

CLOSURE FASTENER.

Application filed May 3, 1923. Serial No. 6 36,3 28.

tion of the margin of the opening is formed t rear wall 9 of T 0 all w 7mm it may comer-n by an edge portion of he s at a right angle Be it known that 1', dessert Mancini, a citizen of the United States, residing at Chicago in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Closure Fasteners, of which the following is a specification.

This invention relates to improvements in closure fasteners, and has reference more particularly to that. type of fastener employing a pin as the main element of the fastening means.

The chief objects of the invention are, to provide a very simple and efficient closure "fastener, wherein the closure is effectively locked in place by the simple operation of driving a fastening pin into closure loclring position, and to provide a closure fastener em )loying a locking pin, wherein the latter when forced into operative relation to the parts engaged thereby shall be automatically rendered incapable of accidental displacement, but may be withdrawn with the aid of suitable tools whenever it is desired or necessary to remove the closure. 7 My invention, its novel structural features, mode of action, and advantages will be readily understood by those skilled in the art from the following detailed de scription, taken in connection with the accompanying drawing wherein l have ill'us t'rated one practical form and application of the invention, and in which Fig. l is an inner side elevation of a portion of the hollow frame or casing of a lift 'ing jack, showing an opening therein, a closure for said opening, and my improved closure fastener applied thereto;

Fig. 2 is a cross-sectional detail on line 22 of Fig. l; and

Fig. 3 is an isolated detail of the locking pin as the same appears before it is driven into closure fastening position.

Referring to the drawing, 5 designates a fragmentary portion of one side wall of a jack frame or casir in which is formed an 0 3611111 6 lun o ioosite the )awls and pawl-controll1ng the jacl: frame which ii to the wall 5; and through the wall 0 is formed a horizontal. hole of a size to lit a locking pin 11..

On the inner side of the closure 7 is cost a lug 12, through which is formed an inclined hole 13, the outer and lower end of which lies directly opposite to the hole 10 in the frame, and is preferably beveled or chamfered, as shown at 13.

On the opposite edge of the closure plate 7 are cast a pair of hock-shaped lugs 14 which, when the closure is applied, engage behind the adjacent vertical margin of the opening, and thus secure the cover-plate against removal on the side.

The cover-plate is applied by first engaging the hook lugs l i with the contiguous margin of the opening, and then pressing the cover-plate into full engagement with its sent. The pin ll, in the straight form shown in Fig. 3, is then driven into and through the registering horizontal and inclined holes 10 and 13 of the frame and lug, respectively. 11s the pin is driven in through the hole 13, it necessarily assumes the bent form illustrated in Fig. l, as a result of which it is automatically locked in closure lasteninw position against any possibility of accidcntal displacement, or removal by purely manual manipulation. However, whenever it is necessary to retract the pin, this can readily be accomplished by inserting an edged tool, such as a chisel, under the head 11 of the pin and prying the latter away from the frame suliicicntly to enable it to be engaged by a claw-bar and fully rctracted: in which operation the pin is automatically brought back to a substantially strai t condition.

lVhilc I have illustrated and described one particular application of my improved closure fastener, it will be understood that the fastening feature is capable of general application in many other situations where a simple and e'llicicnt automatic lock is required not requiring the use of a key to release the closure. The device is especially useful where u 'lplied to articles which are moved about from place to place and may be deposited in any of various positions, since there is no possibility of the locking pin dropping out of place even though the the mechanism (not shown) of the jack and through which the latter may be inspected and gotten at whenever required. '7 designates a removable coverplate for the said opening formed with a countersunk margin 8 on its inner side litting the margin of the opening 6. In the structure herein shown, one vertical porotherwise cause the article to which it is applied should be de posited in a position Where gravitywould pin to fall out.

I claim l. The combination With a member formed With an opening and a hole therein adjacent to the margin of said opening, of a closure fitted to said opening and itself formed With a hole registering with the hole in said member and disposed at an angle to the latter, and a straight fastening pin driven through said holes and therebv bent into self-locking engagement With the latter,

member and inclined relatively to the latter, and a straight fastening pin driven through said holes and thereby bent into self-loeking engagement With the latter.

3. The combination with a hollow frame m mber formed With an opening in a wall thereof and a hole therein adjacent to amarginal' portion of said opening, of a cover-plate fitted to said opening, said cover-plate having on its inner side one or more hook lugs engaged With the opposite marginal portion of said'opening and also a fastening lug formed With a hole registen ing with the hole in said frame member and inclined relatively to the latter, and straight fastening pin driven through said holes and thereby bent into self-locking engagement with the latter.
